Application filed March 6, 1907. Serial No. 360,943.

To all 'whom it may concern:

Be it known that I, ALBERT SGHEIBLE, a citizen ofthe United States, residing at Chicago, in the county of Cook and State of Illinois, -have invented a certain new and useful Improvement in Anchoring Devices, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specication.

My invention relates to anchoring devices, and has for its object the simplified forniation of these devices which at the same time will be very eective in use.

My invention will be fully explained by reference to the accompanying drawin showing one embodiment thereof, and wil be 'pointedout in 'the claims.

The drawing shows 'the preferred embodiment ofthe invention and the manner of thev use of devices made in accordance therewith,

in which 'drawin Figure 1 is a view illustratin a device as it is about to be inserted throug a wall portion. Fig. 2 is a view similar to Fig. 1, with the exception that the device has been projected through an opening in the wallportion, an end of the wall ortion being more fully indicated than in ig. l. Fig. 3 is a view similar to Fi 2, with the exception that the anchor bo t structure has been rotated a half revolution so that the inner portion of the anchor bolt structure will assume the position illustrated. Fig. 4 is a view vin the direction of arrow 4, Fig. 3.

`Like parts are indicated by similar characters of reference throughout the different figures.

The device of my invention is adapted particularly for use in connection with wall portions (the term wall being intended to include in its definition, ceilings or any supporting body with which the device of my invention may be used) that are not readily adapted to have threaded engagement with bolts or screws. Such.l a wall portion .is indicated at a in each of the figures and may, for the sake of explanation, be assuined to be of hollow tiling, as indicated in Fig. 2. This tiling-is shown as provided with a hole b therethrough, of a size sulficient -te admit thepassage of the anchor element c therethrough when said anchor` element occupies the position shown in Fig. 1. The said anchor element is formed of strip lpin metal bent into U-shape, the plane of the U beingparallel with the direction of thrust of the anchor element as it is being assed through the wall. By the expression plane of the U I mean that plane with respectto which the broad surfaces of the anchor element as viewed in Figs. 1, 2 and 3, are perpendicular, and which plane is parallel with the long edges of the anchor element, clearly shown 1n Fig. 4. In other words, the plane of the U is parallel with the plane that contains the long edges of the U, appearing most clearly in Fig. 4.

Apertures d are formed in the limbs of `the U -shaped anchor element, preferably practically half way between the ends of the U and preferably practically half way between thelong edges of the strip metal forinin-g the anchor-element. A union e (in the embodiment of the invention shown, this union being' a nut) is desirably provided With;trunnion projections f that are inserted within the apertures d. In order to permit of this assembly of the nut and anchor element, the limbs of the anchor element are spread apart su'iciently to permit of the alinementof the ears f with the apertures d, wliereafter said limbs are approached until the said ears f are sufficiently projected through the said apertures. I desirably employ distance preserving means to prevent the limbs from becoming separated after they'have been thus approached, which distance preserving means desirably resides in a having a head g1 at one end engaging one limb of the anchor element and having its other end bent over at g2 to engage the other limb of the anchor element. The pin g prevents the limbs from spreading and the nut e prevents the limbs 'from collapsing. A shaft It is coupled with the anchor element. In the embodiment of the invention shown this shaft z, is the threaded shank of a bolt having threaded connection with the nut c which constitutes the union between the bolt shank and the anchor element.

lVhen the structure is to be passed through i being of suliicient weight to equal the addiformation, whereby they may be adapted to j acteristic is to be provided, the means of *A provided with ay head Z inte rection (with the parts positioned as shown in Fig. l). This structural feature may, if desired, also reside in the pin g, which is caused to rest against the shank la, since the portion of the anchor element to the left of the trunnions j is heavier than the portion of said anchor element to the ri ht of said trunnions, this additional weight eing preferably afforded by the metal in the curved end z' of the anchor element, the pin g not tional weight supplied at z'. While I prefer to provide the preponderating weight at the bend of the U, I do not wish to be limited to this characteristic. Thus the parts when positioned as indicated in Fig. 1, may be thrust through the aperture b as indicated in Fig. 2, whereafter when the shank lz, is turned a half revolution, the anchor element will assume a vertical position, because the preponderating weight at z' is no longer resisted by the engagement of the pin g with the shank h, said pin having been disposed above said shank when said shank was turned a half revolution. When the parts are in the position shown in iFigs. 1 and 2, the anchor element extends longitudinall of the shaft l1., the element g being so positioned as to permit this disposition of the parts as the anchor element is being thrust through the wall. It is, of course, understood that the nut e turns bodily with the shank, in order that the pin g may be disposed above the shank to permit the anchor element to assume the position shown in Fig. 3. The shanks z, may be of suitable different purposes. They are threade where united with cthe anchor element, when it is intended'to have the anchor element moved bodily along the same, and vwhenthis charattachment between the bolt shank and the anctzhor element is preferably the threaded nu e.

I do not wish to be limited to a construct1on, however, wherein the anchor element is to be moved bodily along the shaft IL. The bolt shank, for. many purposes, is referably al y formed therewith, which head may, ildesired, have a: screw-driver slot. I do not wish to'be. limited, however, to the presence ofa head upon theelement It.

The advantage of my improved construc-L them that it has been customary hitherto for the user to hold the anchor bar parallel to the shaft'when inserting the anchor bar, so as not to have this bar catch on the outside of the wall. It is frequently diihcult `for the installer to thus hold the anchor element and shaft in arallel relation.

Having thus descrl d my invention, l

claim as new and desire to secure by Letters- Patent 1. A device of the class described comprisv ing an anchor element formed of strip metal bent into U-shape, the plane of the U being substantially parallel with the direction of thrust of the anchor element when being inserted, a shaft, and a nut having trunnions projecting through openings in the sides of the anchor element and having threaded engagement with the shaft, said nut affording pivotal connection between the shaft and anchor element, there being means for limiting the rotation of said anchor element in one direction to enable said anchor element and shaft to be disposed and held longitudinally of each other when said anchor element is to be passed through an opening, the portions of the anchor element upon opposite sides of the pivotal connection thereof with the shaft being of unequal weight, the preponderating weight acting when the parts are in one position, to cause, or tend to cause, the rotation of the anchor element in the aforesaid direction of rotation, the aforesaid limiting means oo-acting with this preponderating weight to maintain the anchor element and shaft in substantial alinement during the passage of the anchor element through an opening, said pre onderating weight serving to swing the ancliorin element at an angle` when the shaft an anchoring element are given substantially a half turn about the axis of the shaft. w

2. A device of the class described comprising an anchor element formed of strip metal bent into U-shape, the plane of the U being substantially parallel with the direction of thrust of the anchor 'element when being inserted, a shaft, and a nut having trunnions projecting through openings in the sides of the anchor element and having threaded engagement with the shaft, said nut aording pivotal connection between the shaft and anchorelement, there being means for holding the anchor element and shaft in alinement as said anchor element is being passed through an openin 3. A device of the class escribed comprising an anchor element formed of strip metal bent into U-shape, the plane of the U being substantiall parallel with vthe direction of thrust of te anchor element when being inserted, a shaft, anda nut having trunnions projecting through openings in the sides of the anchor element and having threaded engagement with the shaft, said uut affording pivotal connection between the shaft and anchor element. l

4. A device of the class described comprising an anchor element formed of strip metal 'bent into U-shape, the plane of the U being substantiall parallel with the direction of thrust of t e anchor element when being inserted, and a shaft pivotall connected with the anchor element, there ein means for limiting therotation of said anc orl element in one direction to enable said anchor element and shaft to be disposed and held longitudinally of each other when said anchor element is to be passed throu h an opening, the portions of the anchor e ement upon opposite sides of the pivotal connecf tion thereof with the shaft being of unequal Weight, the preponderating weight acting when the parts are in one position, to cause, or tend to cause, the rotation of the anchor element in the aforesaid direction of rotawith this preponderating Weight to maintain the anchor element and shaft in substantial alinement during the passage of the anchor element through an opening, said preponderating weight serving to swlng the anc orin element at an angle when the shaft an anchoring element are given subA stantially a half turn about the axis of the shaft.

' In witness whereof, I hereunto subscribe my name this 27th day of February A. D., 1907.
